This International Standard describes a method for the determination of gross alpha and beta activity in non-saline waters for alpha and beta-emitting radionuclides.The method is applicable to raw and potable waters containing a small quantity of dissolved matter.It must be adapted for other kind of waters.The range of application depends on the amount of dissolved material in the water and on the performance characteristics of the measurement equipment (background count rate and counting efficiency).
